Question 12.36:
In the organic compound CH2=CH–CH2–CH2–C≡CH, the pair of hydridised orbitals involved
in the formation of: C2 – C3 bond is:
(a) sp – sp2 (b) sp – sp3 (c) sp2 – sp3 (d) sp3– sp3

 

CH26=C5H-CH42-CH32-C2=C3
In the given organic compound, the carbon atoms numbered as 1, 2, 3, 4, 5, and 6 are
sp, sp, sp3, sp3, sp2, and sp2 hybridized respectively. Thus, the pair of hybridized orbitals
involved in the formation of C2-C3 bond is sp – sp3.
